Mediant 1000B Gateway & E-SBC
Tel Profile Parameter Global Parameter
 FXO Interfaces: The device releases a call when a
current disconnect signal is detected on its port.
FXS Interfaces: The device generates a 'Current
Disconnect Pulse' after the call is released from the IP
side.
Note:
ï‚§ The parameter is applicable to FXS and FXO interfaces.
ï‚§ The current disconnect duration is configured by the
CurrentDisconnectDuration parameter.
ï‚§ The current disconnect threshold (FXO only) is configured by
the CurrentDisconnectDefaultThreshold parameter.
ï‚§ The frequency at which the analog line voltage is sampled is
configured by the TimeToSampleAnalogLineVoltage
parameter.
ï‚§ The corresponding global parameter is
EnableCurrentDisconnect.
DID Wink
enable-did-wink
[TelProfile_EnableDIDWink]
Enables Direct Inward Dialing (DID) using Wink-Start signaling,
typically used for signaling between an E-911 switch and the
PSAP.
ï‚§ [0] Disable (default)
ï‚§ [1] Single = The device can be used for connection to
EIA/TIA-464B DID Loop Start lines. Both FXO (detection) and
FXS (generation) are supported:
FXO Interfaces: The device dials DTMF (or MF) digits
upon detection of a Wink signal, instead of a dial tone.
FXS Interfaces: The device generates a Wink signal upon
detection of an off-hook state, instead of playing a dial
tone.
For example: (Wink) KP I(I) xxx-xxxx ST (Off Hook)
Where:
I = one or two information digits
x = ANI
Note: The FXO interface generates such MF digits when the
Enable911PSAP parameter is set to 1.
ï‚§ [2] Double Wink = Double-wink signaling. This is applicable to
FXS interfac
es only. The device generates the first Wink upon
detection of an off-hook state in the line. The second Wink is
generated after a user-defined interval (configured by the
TimeBetweenDIDWinks parameter) after which the DTMF/MF
digits are collected by the device. Digits that arrive between
the first and second Wink are ignored as they contain the
same number. For example:
(Wink) KP 911 ST (Wink) KP I(I) xxx-xxxx ST (Off Hook)
ï‚§ [3] Wink & Polarity=
FXS Interfaces: The device generates the first Wink after
it detects an off-hook state. A polarity change from
normal to reversed is generated after a user-defined time
(configured by the TimeBetweenDIDWinks parameter).
DTMF/MF digits are collected by the device only after this
polarity change. Digits that arrive between the first Wink
and the polarity change are ignored as they always
contain the same number. In this mode, the device does
